Model: A-1446-110-40
Material: Zinc Alloy | Finish: Powder Coating | Rating: IP65, UL FTTA2/FTTA8 Class 1
Product Description
The A-1446-110-40 is a small compression-type door lock with sealed lever and key-controlled access, designed for enclosure doors and access panels requiring secure, sealed closure with managed key control. If you’re building compact industrial cabinets, equipment housings, or electrical enclosures where security, sealing performance, durability, and reliable operation are critical, this lock delivers comprehensive functionality in a space-efficient package.
The lock body is manufactured from zinc alloy with a powder coating finish in black — a durable combination that resists corrosion and impact while maintaining its appearance over extended use in demanding industrial environments. The powder coating provides superior resistance to scratches, abrasion, and incidental contact compared to plated finishes, making it practical for high-traffic applications or installations where the door or panel faces regular physical exposure.
The key locking system uses the CH751 key cylinder with integrated dust cover, providing controlled access that requires the correct key to unlock and open the door. The dust cover protects the key cylinder from environmental exposure, dust accumulation, and incidental contact — extending the operational life of the cylinder mechanism. This key-controlled restriction is essential for applications where security and access management matter — whether you’re protecting sensitive equipment, preventing unauthorized opening, or maintaining secure control across multiple cabinet installations. The CH751 cylinder is a proven, industry-standard design offering reliable pick resistance and smooth, consistent operation.
What makes this lock effective is the integrated sealed lever design. The sealed lever works in combination with the compression mechanism to create a comprehensive seal between the door and frame. As the lock closes, the compression movement pulls the door tightly into position while the sealed lever ensures uniform contact and proper engagement. This dual-action approach significantly improves sealing performance, reducing friction and wear on both the latch mechanism and door frame while maximizing protection against dust and moisture ingress.
The small form factor makes this lock ideal for applications where space is limited or where a more compact locking solution is preferred. Despite its smaller size, it maintains full performance specifications and comprehensive sealing capability.
The low-profile design keeps the external face clean and streamlined. The concealed installation hides mounting hardware from view, which improves aesthetics while protecting brackets and fasteners from incidental impact or environmental exposure. The adjustable grip accommodates different panel and door thicknesses, eliminating the need for custom modifications across varying applications.
Performance is backed by documented specifications. The handle bearing tension value is rated at ≤ 750N, ensuring reliable operation even under repeated use. The maximum static load rating of 200N provides sufficient load capacity for typical cabinet and enclosure door applications. These performance parameters ensure the lock performs consistently throughout its operational life.
The A-1446-110-40 carries IP65 protection, meaning it resists dust ingress and water spray from any direction. Combined with UL FTTA2 / FTTA8 Class 1 compliance, it’s suitable for industrial, telecom, and commercial applications where certification and documented performance standards are required.
